​​Introduction to vsigupdate_OS7.2.0_91.09447_FWET.pkg Software​​

This critical security update package (build 91.09447) addresses 18 vulnerabilities in FortiOS 7.2.0 deployments, including 4 high-risk CVEs affecting SSL-VPN and IPv6 routing subsystems. Designed for enterprise-grade FortiGate 300E/400F/600F firewall series, it enhances threat prevention capabilities while maintaining backward compatibility with SD-WAN topologies configured through FortiManager 7.4.5+.

The firmware supports hardware models with NP7 network processors and 16GB+ RAM configurations. Released on April 25, 2025, it introduces automated vulnerability patching workflows compatible with FortiAnalyzer 7.6.3+ for centralized compliance reporting.
